vIMPROVEMENT IN HAYSPREADERS.\

The Schedule :referred to :in these Letters Patent making part of thesame.A

To all whom it may concern Be it known that I, GILBERT I. WoosTna, ofPlymouth, in the county ofrLtchield and State of Connecticut, haveinvented a new Improvement in Il :1y-Spreader; and I do hereby declarethe following, when taken iu connection with the accompanying drawingsand the letters of reference marked thereon, to bea full, clear, andexact description of the same, and which said drawings constitute partof this specih'cation, aud-represent in- Figure 1, a top view,

Figure 2, a side view, andin Figure 3, a longitudinal central section.

This ,invention relates to an improvement in machines for spreadingnew-niown hay, and consists in the arrangement of the crank-shaft, sothat bythe same operation -it is thrown out of "gear and the forksraised. v

A A are two ends of the frame, attached together by two cross-bars, B C,and supported. upon an axle, I), on which are arranged wheels E E, uponwhich the l nrichine is moved.

FF are two crank-shafts, driven, by connection with the wheels E,through gears f f.

u are the forks, each attached to its respective crank el, so t-hat thecrank will turn freely therein, the upper end of the fork passing upthrough a fixed bar, I, ,but playing freely in the said bar; therefore,as the cranks revolve, the forks will be thrown 'from the positiondenoted at a, tig. 2, forward to the position at a in the same figure.The upper end being held by the bar I, the whole movement of the crankis imparted to the fork or lower end only.

The crank-shaft F is arrangedii-u Vblocks L L L,'

each hinged to its respective part' of the frame, asin figs 2'and 3, andfrom the central block a lever, I,

Als it is necessary, iu order to the opera-tion of the forks, that thecrank-shaft shouldalways be the saine distance from the gronmhsomeadjustment must he luadefor the dil'ferent'height-s of` horses. To dothis, I .hinge the shafts R R to the bar ILL-as at s, and secure theshafts adjustably t-o the bar C by screws t, or otherwise, so that theshafts may begraised or lowered tolacconimodate the height of the;horse.
